Applications of Rubber Lined Slurry Pumps

Especially when the dredging depth reaches 20m or more, the above situation will be more obvious. The use of underwater pumps can effectively improve the above situation. The lower the installation position of underwater pumps, the smaller the suction resistance and vacuum, which can obviously reduce the losses during the work and improve the working efficiency. The installation of underwater pump can effectively increase the dredging depth and improve the ability to transport sediment.

The FGD process begins when the limestone feed (rock) is reduced in size by crushing it in a ball mill and then mixed with water in a slurry supply tank. The slurry (approx. 90% water) is then pumped into the absorption tank. As the consistency of the limestone slurry tends to change, suction conditions can occur which can lead to cavitation and pump failure.

The design of the slurry pump is critical to ensure that the abrasive and often corrosive aspects of the slurry do not damage the impeller. In addition, slurries and sludges may contain large amounts of unforeseen solids, which will inevitably clog many types of pumps. Since most centrifugal pump impellers have very tight tolerances on the worm gear, the abrasive (and sometimes corrosive) nature of the slurry will quickly wear down the worm gear and destroy the tolerances. In turn, this causes the pump to lose suction. This can lead to extensive downtime of the slurry pump, as well as expensive maintenance and spare parts.
